How long does an uninterruptible power supply last?

Like all other IT equipment, an uninterruptible power supply (UPS) has a finite lifespan. The average expected lifecycle of a UPS is eight-to-ten years. The batteries typically need to be replaced at least three times during that lifespan. Of course, once a UPS reaches the end of its lifespan, it should be replaced to mitigate downtime.

What is a UPS (uninterruptible power supply)?

A UPS (Uninterruptible Power Supply) is an emergency power system that provides backup power when the main source of power is lost. It gives businesses valuable time to safely power down machinery or keep critical systems online until backup generators kick in.

How long can a ups last without power?

Discover how long a UPS can last without power—from 1 to 8 hours! Learn about UPS battery life, runtime, and factors affecting performance.

What is a ups & how does it work?

A UPS bridges the gap between the power outage and the restoration of electricity or the time to safely shut down devices. It consists of a battery backup, an inverter, and a rectifier. Battery Backup: Stores energy to supply power when the main source fails. Inverter: Converts stored DC power to AC power for your devices.
